Cloudflared

From ArchWiki

Cloudflared may be used to run a local DNS over HTTPS server (DoH), i.e., a stub resolver.

Installation

Install the cloudflared package.

Configuration

Cloudflared by default ships with 1.1.1.1 and 1.0.0.1 enabled, with the DNS server runing at port 5300, and the server only accessible to localhost.

To change the configuration, edit the following file, replacing <endpoint> with preferred endpoints.

/etc/cloudflared/config.yml
---
logfile: /var/log/cloudflared.log
proxy-dns: true
proxy-dns-upstream:
 - <endpoint>
 - <endpoint>
 - <endpoint>
proxy-dns-port: 53
proxy-dns-address: 0.0.0.0

As per upstream documentation, here are the available endpoints:

Tip: cURL's documentation maintains a list of alternative public endpoints.
